Below in conjunction with accompanying drawing this preferred embodiment is described.
Fig. 9 is according to the AS of the embodiment of the invention flow chart to user's subscribed services device activated terminals; As shown in Figure 9; AS issues the request of activated terminals to mobile management network element (for example, MSC, SGSN or MME) via user's subscribed services device (for example, HLR or HSS); Mobile management network element will activate message through suitable message (for example, descending NAS message, Paging message etc.) and be handed down to the terminal.Thereafter, terminal active and AS set up the IP communication.This flow process comprises the steps:
Step S902, AS wherein carries service identifiers to the request that user's subscribed services device sends activated terminals;
Wherein, said service identifiers is the sign of AS, also can is the sign of the service that realizes of AS.
Step S904, user's subscribed services device is searched suitable mobile management network element, and the request of will activating is transmitted to mobile management network element;
Step S906; Mobile management network element will activate request and be handed down to the terminal, after the request of activation is received at the terminal, according to service identifiers; Can know that which business need terminal is activated or which AS has sent the request of activation, thereby can on purpose initiate the IP communication to AS.
Above-mentioned steps can be applied to the terminal of following situation: the terminal that has been attached to network: in this case, the terminal possibly be assigned with the IP address, then can directly initiate the IP communication to AS.The terminal possibly not have distributing IP address (adhere to as having only GPRS, do not set up PDP Context) yet, and then the foundation that IP carries need be initiated in the terminal, distributes to such an extent that initiate the IP communication to AS again behind the IP address; Be not attached to the terminal of network: in this case,, can monitor the broadcast of this network even require the terminal not to be attached to certain network yet; Require user's subscribed services device can select suitable mobile management network element to issue the request of activation; Require mobile management network element not having under the contextual situation in terminal, also can be issued to the base station activating request.
Figure 10 be according to embodiment of the invention terminal attached in the network, AS is to the flow chart of user's subscribed services device activated terminals, and is shown in figure 10, this flow process comprises the steps:
Step S1001, AS sends the request of activation to user's subscribed services device (for example, HLR or HSS), carries service identifiers; Wherein, carrying of service identifiers is in order to let the terminal know that which service needed activated terminals or which AS hope activated terminals and initiate communication.Such as: MTC is used, and this service identifiers shows it is that the MTC application server is hoped activated terminals.Should have SUPL, this service identifiers shows it is that SUPL location-server (SLP) is hoped activated terminals.
Step S1002, after user's subscribed services device receives the activation request of AS, the Mobility Management Entity of inquiry terminal current register (for example, MSC, SGSN or MME), the request of will activating sends to this Mobility Management Entity; In this step, user's subscribed services device can use existing accessibility inspection message, and in this message, carries sign and require the mobile management network element activated terminals.Said sign should be carried the service identifiers among the step S1001.Perhaps, can newly introducing independently, message requires activated terminals.
After step S1003, Mobility Management Entity receive the request of activation, use NAS message activation terminal; In this step, mobile management network element carries the service identifiers among the step S1001 in NAS message, with activated terminals.This NAS message can be to carry in existing NAS message to activate sign, also can be the message that is used for activated terminals that increases newly.
Step S1004, response is returned after receiving the request of activation in the terminal;
Step S1005, the terminal is initiated the IP communication according to the service identifiers that activates in the request to specific AS.
In above-mentioned steps, mobile management network element sends NAS message with activated terminals to the terminal.Mobile management network element can also send Paging message activation terminal to the terminal, and for example, mobile management network element can use the Paging message of enhancing to come activated terminals, wherein carries the service identifiers among the step S1001.
Figure 11 be according to the embodiment of the invention the terminal not attached to network in, AS is to the flow chart of user's subscribed services device activated terminals, this scheme shown flow process and flow process shown in Figure 10 similar, but have following difference:
In step S1102 (this step is the step that increases than Figure 10); When user's subscribed services device (for example; HLR or HSS) receive the activation request of AS after, need to seek suitable mobile management network element (for example, MSC, SGSN or MME); User's subscribed services device can be selected through following mode: for the terminal of not supporting to roam and have Hypomobility: according to the mobility scope that is limited in signatory, select suitable mobile management network element; User's subscribed services device (HLR/HSS) is preserved the mobile management network element that last time, the terminal was registered, and can set a suitable timer, after timer exceeds the time limit, removes the mobile management network element of being preserved; Then, in effective time, think that this terminal still might be in the coverage of this mobile management network element at this timer.
In step S1104, mobile management network element uses Paging to come activated terminals, in the Paging parameter, carries the service identifiers among the step S1201, the ID at terminal.For the terminal that is not attached to network, the Paging message of must having the ability to monitor.When the terminal listens to the request of activation from Paging message after, need to initiate the network attachment flow process, initiatively initiate communication then to AS.
In flow process shown in Figure 11, AS generally knows that it is the application layer sign at terminal, and is IMSI in order to what identify a terminal in user's subscribed services device (HLR/HSS).Though user's subscribed services device (HLR/HSS) can be set up mapping relations between the application layer at terminal sign and IMSI; Yet; Paging message is not supported the application layer sign at present; Thereby in the Paging message that mobile management network element (MSC/SGSN/MME) issues, entrained Termination ID need use IMSI.This method is exposed to IMSI in the network, increases insecurity widely.
In order to solve the security threat that flow process shown in Figure 11 is brought; When terminal during from the network attachment removal, the temporary mark that mobile management network element (for example, MSC, SGSN or MME) will be distributed to the terminal (for example; In the CS territory is TMSI; In the GPRS territory is P-TMSI, is GUTI in the EPS territory) be saved in user's subscribed services device (HLR/HSS), thus make follow-up Paging can use the terminal temporary mark of this preservation.Further, mobile management network element or user's subscribed services device also can send to application server with this temporary mark.
Figure 12 is the use temporary mark of embodiments of the invention, and AS is to the flow chart of user's subscribed services device activated terminals, and is shown in figure 12, and this flow process comprises the steps:
Step S1201, the flow process from the network attachment removal is carried out at the terminal;
Step S1202, mobile management network element sends to user's subscribed services device through notification message for the temporary mark (for example, TMSI, P-TMSI or GUTI) at terminal network allocation; Wherein, this step can comprise two kinds of modification: S1202a, and network allocation is sent out to AS for the temporary mark at terminal and is preserved; S1202b, said temporary mark only are stored in and are used for the subscribed services device.
Step S1203, AS initiates the request of activated terminals, carries service identifiers, Termination ID;
In this step, if the temporary mark that aforementioned network is distributed to the terminal among the step S1202 is transmitted to AS, then AS can use this temporary mark as Termination ID.Otherwise AS possibly use the application layer sign, IMSI at terminal as terminal iidentification.
Step S1204 after user's subscribed services device is received the request of activation, searches suitable mobile management network element;
In this step, user's subscribed services device replaces with the Termination ID in the activation request temporary mark at the terminal of being preserved among the step S1202 according to mapping relations.
Step S1205～S1210 can adopt step shown in Figure 11, repeats no more at this.
To not adhering to the terminal, adhering to the d/d terminal of single radio bearer, can adopt beep-page message Paging to come activated terminals.In Figure 10,11, the flow process shown in 12, Paging message is enhanced, to carry service identifiers.This mode is bigger to the transformation cost of radio call message.Figure 13 is that the use beep-page message according to the embodiment of the invention comes activated terminals; Use NAS message to send the flow chart of service identifiers; Figure 13 has described a kind of mode; Use beep-page message Paging to come activated terminals, yet the download of service identifiers is after UE and core net have been set up NAS and be connected, and sends service identifiers through NAS message to the terminal by mobile management network element.Adopt the mode of Figure 13, beep-page message Paging does not need to transform, and has reduced the upgrade cost of system.Shown in figure 13, these flow process following steps:
Step S1301, mobile management network element receive terminal activation request, wherein carried terminal sign, service identifiers;
Step S1302～S1305, mobile management network element use existing beep-page message Paging to come call terminal, the terminal response beep-page message;
Step S1306 does not adhere to the terminal and carries out the process that is attached to network, request distributing IP.Adhere to the terminal and initiated services request, set up wireless, core net carrying;
Step S1307, the mobility network element is handed down to the terminal through NAS message with service identifiers.Through this service identifiers, the terminal can know which service needed activated terminals or which application server needs activated terminals;
Step S1308, terminal active and application server are set up the IP communication.
Need to prove, in the scheme of the activated terminals of preferred embodiment two, require service identifiers is handed down to the terminal, set up communication to impel terminal active and server.Yet, for regularly only with the terminal of single AS communication for, the activation behavior can be simpler: AS issues the request of activation through core net and gives the terminal, can not carry service identifiers therein; After the request of activation is received at the terminal, always unconditionally attempt and the AS communication.
Obviously; It is apparent to those skilled in the art that above-mentioned each module of the present invention or each step can realize that they can concentrate on the single calculation element with the general calculation device; Perhaps be distributed on the network that a plurality of calculation element forms; Alternatively, they can be realized with the executable program code of calculation element, carried out by calculation element thereby can they be stored in the storage device; Perhaps they are made into each integrated circuit modules respectively, perhaps a plurality of modules in them or step are made into the single integrated circuit module and realize.Like this, the present invention is not restricted to any specific hardware and software combination.
